used mitochondrial (COI) and nuclear (Histone H3) genome markers to test the hypothesis that the diversity of Treptopale (Annelida: Chrysopetalidae) in northern Australia comprises more than the two currently known species recently described based on morphology. The molecular phylogeny reveals nine clades. The Treptopale homalos species complex comprises: T. homalos sensu stricto, Selleckchem AZD2171 the only clade occurring all around northern Australia (from Heron Island to Ningaloo Reef); Clade 8 found only at Ningaloo Reef; Clade 2 found only on the Great Barrier Reef and described here as new. Treptopale magdae sp. nov. can be distinguished morphologically by the smaller number of internal ribs of the lateral, main and medial paleael notochaetae. The diverse Treptopale paromolos species complex comprises six clades: Clade 3, Treptopale paromolos sensu stricto selleck kinase inhibitor and Clade 5 are only found on

Australia’s NW coast; Clades 4, 6 and 9 are found only in NE Australia. Molecular phylogenetic relationships, especially those using mtDNA COI, suggest that Australian east and west coast populations of the T. homalos and T. paromolos lineages have diverged a number of times. The highest diversity of Treptopale clades is found within the complex micro-patch habitats of NE and NW Australia’s major coral reef systems. The low diversity of Treptopale clades found in the north (Darwin Harbour) and northwest (Scott Reef) is related to the presence of less complex reefal systems and a corresponding lack of coral habitat diversity.”
“The beta-xylosidase encoding gene (XsidB) of the extremely thermophilic bacterium Geobacillus thermodenitrificans has been cloned and expressed in Escherichia coli. The homotrimeric recombinant XsidB is of 204.0 kDa, which is optimally active at 60 degrees C and pH 7.0 with T-1/2 of 58 min at 70 degrees C. The beta-xylosidase remains unaffected in the presence of most metal ions and organic solvents. The K-m [p-nitrophenyl beta-xyloside (pNPX)], V-max and k(cat) values of the enzyme are 2 x 10 (3) M, 1250 mu P5091 mouse moles mg (1)

min (1) and 13.20 x 10(5) min (1), respectively. The enzyme catalyzes transxylosylation reactions in the presence of alcohols as acceptors. The pharmaceutically important beta-methyl-D-xylosides could be produced using pNPX as the donor and methanol as acceptor. The products of transxylosylation were identified by TLC and HPLC, and the structure was confirmed by H-1 NMR analysis. The enzyme is also useful in synthesizing transxylosylation products from the wheat bran hydrolysate. (C) 2014 Elsevier Ltd. All rights reserved.”
